Phone battery

Today, everyone has a smartphone. This rectangular brick has literally conquered the world. While the device is quite useful, unfortunately, it lacks battery life. Phone batteries have a short lifespan. Typically, they need to be replaced after 2-3 years. Let's figure out which battery to buy.

Battery for phone and smartphone

Good to know!

Today, many batteries are equipped with a charge controller. This device helps monitor the charging and discharging process. Furthermore, if an emergency occurs—for example, if the battery gets too hot—the controller will shut it off. The same will happen if the battery cools down.

How to choose a battery for your phone?

Tips before choosing:

1. The capacity rating. The higher the rating, the longer the device can operate. mAh stands for capacity in milliamp hours.
2. A complete match to the old battery. Identical type to the previous battery.
3. Voltage. Typically, it starts at 3.7 volts. Some models may have higher or lower voltages.
4. The size must match the old battery.
5. Contact arrangement.
6. What type? Lithium-ion or other.
7. Before purchasing a battery, check your smartphone's technical specifications. They usually specify the specific battery type required.
8. Price. Sometimes manufacturers mislead consumers. They sell batteries with supposedly high capacity for a small price, but at a low price. Be careful, as these batteries are of poor quality and their capacity is much lower than stated.
9. Warranty. Each manufacturer provides its own. The average lifespan of a phone battery is 1 year. Typically, this ranges from 6 months to 3 years.
10. It is best to purchase a Li-ion (they have an automatic shut-off when fully charged) or Li-pol battery for your phone.
11. How many times can a battery be discharged and charged? The most common is 1000 times.
12. The case, how durable is it? Preferably, it should be aluminum.
13. Ask the seller if there is protection and if there is a thermostat.

The battery life of a phone is affected by:

1. Screen type
2. Networks: GPS, Wi-Fi, 3G, 4G.
3. Supported functions.
4. Backlight.
5. The delivered program.

Frequent charging of the battery leads to its rapid wear!

Types of phone batteries

After analyzing the history of battery development, it turned out that there are only 4 types of batteries for phones.

Nickel-cadmium batteries (Ni-Cd)

This type of battery was first manufactured back in 1899. Due to numerous shortcomings, it never gained widespread popularity. However, it is quite durable and long-lasting. It can withstand extremes of high and low temperatures and can be recharged multiple times.

The main drawback that outweighs all the advantages is their toxicity. Cadmium is a poisonous substance. Furthermore, this type of phone battery has low energy capacity. Production costs are very high. And the occasional memory effect requires frequent replacement. calibrationThis is not very convenient.

Nickel metal hydride batteries (Ni-MH)

These batteries are nickel-based. Their main advantage is their high capacity and low production costs. Previously, this type of battery was used in large, budget-friendly phones with limited functionality.

Their main drawback is the memory effect. You charge the phone when the battery indicator reaches 30%, and then it shuts off when it reaches that level. This effect is less pronounced than with the type described above. These batteries also take a long time to charge.

Lithium-ion batteries (Li-Ion)

This type is currently the most popular! Their main advantage over competitors:

1. Compact dimensions.
2. Big capacity.
3. Low self-discharge.
4. No memory effect.
5. They demonstrate stable performance.

These mobile phone batteries work stably and for a long time.

The downsides include their high cost compared to nickel-based batteries. They don't handle cold well. At -20°C ⁰There's a risk of electrolyte leakage. These power supplies shouldn't be left discharged. Their service life may be reduced. They are subject to wear and tear regardless of whether they're used or not.

Lithium-polymer batteries (Li-Pol)

This removable smartphone battery is manufactured using lithium salts and a polymer electrolyte. This approach allows for the creation of a variety of phone charging battery shapes. Thinness and flexibility are the key features of these batteries.

Pros:

• High energy capacity, approximately the same as lithium-ion internal batteries for phones.
• The cost is significantly lower than those described above.
• High number of charge/discharge cycles.

Cons:

• They operate unstably at low temperatures.
• Severe overcharging and deep discharge are harmful. A voltage controller is built in to prevent this. This affects the product's cost.

Reinforced batteries for phones

These models are also called powerful batteries with increased capacityUnlike power bankThey have compact dimensions. Their dimensions are the same as the device's original battery. These devices are most often made in China or Japan.

The basic battery capacity ranges from 2450 mAh to 5500 mAh. These battery characteristics significantly extend the life of your smartphone and unlock its full potential.

• Large capacity.
• Possibility to recharge a portable battery for your phone multiple times.

How to choose Power bank for phone?

When buying a travel battery for your phone, pay attention to the following things:

• Dimensions. Decide what you're going to use the backup for. power bankIf you're buying a phone case, it should fit easily in your pocket, bag, or backpack. Keep in mind that the dimensions should be optimal. A 12,000 mAh battery won't fit in a small case.
• The material it's made of. A metal case is durable but quite heavy. Plastic is much lighter. If the power bank won't be used in extreme conditions, then a plastic one is fine. The case doesn't affect stability.
• Capacity. It should be twice the capacity of the installed battery. Naturally, the higher the better. It's recommended to purchase an additional 6000 mAh power bank, but if your budget is tight, a 4000 mAh one will suffice.
• Current. Batteries usually contain this information on the label. It is typically 0.5-1 amp.
• Charging. It's best to buy a device that can charge both via USB and a wall outlet. This type of USB phone battery is called a hybrid. Preferably, it should have a current of 1-2 A.
• Features such as a charging indicator, a power button, and the number of USB ports are all user-selectable. Their only benefit is convenience.
• Make sure the on/off button is fully recessed into the housing. This will prevent accidental activation.

A portable battery has a voltage of 3.7 volts. Smartphones and other mobile devices require a charge of 5 volts. This means a loss of up to 30% of the battery's energy potential. Cheap Chinese batteries typically have only 50% of their stated capacity.

How it works power bank?

A spare storage battery for a phone functions in the same way as a simple battery built into a mobile smartphone.

A series of power cells are soldered into the power controller. Then, ports for recharging the battery are integrated. Then, one or more ports for charging the smartphone are installed.

We connect the Power Bank to the phone, and its battery begins charging! Electric current flows from the donor to the smartphone's additional battery.

How much does a power bank cost?

Phone battery prices depend on the capacity; the larger the capacity, the higher the price. For example, a power bank with a 10,000 mAh capacity can be found for 2,000 rubles. A 5,000 mAh one, however, can be purchased for 1,000–1,500 rubles.

How to use a phone power bank battery

1. Changing the external battery phone batteryWhen installing a new one, you must turn off the power to the device. Otherwise, the memory may become corrupted.
2. To expand a little capacityPerform up to 5 discharge-charge cycles. This means completely discharging the external battery and charging it to 100%.
3. Avoid moving your portable phone battery abruptly from warm to cold temperatures and back. Allow it to sit for a while and reach room temperature before charging.
4. Do not recharge for more than 24 hours. Once the battery is fully charged, a special chip will stop charging.

The best solution is to purchase a Power Bank for 6,000 – 12,000 mAh.
